The UK’s Computer Arts magazine has a useful mini-tutorial on how to use @font-face to style web type

“The @font-face command and Web Open Font Formats (.woff files [containers for normal fonts]) now enable designers to create and link to a specific, traditionally non-web-safe font in all modern browsers. […] When a visitor lands, either the @font-face font is linked to [on their PC], or the .woff file is uncompressed within the browser, making the font available even if your viewer doesn’t have it”
